Photo Information for NGC7635 Bubble Nebula and M52 in Ha


Recommended Comments

That's an excellent image, thanks a lot for posting!  Us observers really need stuff like this to understand what we are seeing in the eyepiece.  I've recent had another shot at this area under moderately light polluted skies and NGC7536 is always what jumps out at me. In your image he is just above the claw and provides the most contrast between bright object and dark background. 

The bubble itself is huge!!!  I was looking for something smaller which might explain why I felt I could see nothing.

Thank you

I can’t imagine trying to see the Bubble visually. It’s barely visible in a 2 minute L sub though it’s a lot clearer with the Ha filter. I’d need much darker skies.
